vCHURN.

SPECIFICATION forming part of Letters Patent No. 565,330, `dated August 4, 1896.

Application led April 25, 1896.

To all whom it may concern.-

Be it known that I, PETER CATINNA, of Columbia, in the county ofl Maury and State of Tennessee, have invented certain new and useful Improvements in Churns; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forni part of this specification.

This invention is an improvement in churns, and its object is to provide an improved and simple mechanism for converting the vibratory movement of a lever into a rotatory niotion of the churn-dasher.

The invention consists in the novel construction and combination of parts herein described and claimed, and as illustrated in the accompanying drawings, in Awhich- Figure l is a side elevation ofthe churn complete, the churn-body being shown in vertical section. Fig. 2 is a transverse section on line 2 2, Fig. l, looking down. Fig. 3 is a detached perspective view of the bifurcated end of the vibrating lever.

A designates the churn-body, of ordinary contour, having a central stud'a in its bottom. When in use, the churn-body is placed on one end of a base B', which has lugs b b to retain the churn-body in position, and on the base beside the churn-body is a casting C, which curves up and over the churn-body and has an adjustable thumb-bolt c in its upper end, directly over the churn, adapted to engage a socket CZ in the upper end of an auger-twist casting D, which has a socket in its lower end in which is secured the upper end of the shaft e of the churn-dasher E, which is of any suitable construction, the lower end of shaft e being stepped on the stud a in the bottom of the churn, so that when in place the dasher is held upright and can be easily rotated on 'its axis.

The twist portion of casting D is of acute pitch and is engaged by the bifurcated end of anoscillating lever F, pivoted in a slot in casting C, as shown. .The bifurcated end of lever F is just wide enough to neatly embrace the twist portion of casting D, and each Serial No. 589,076. (No model.)

arm of the bifurcation has an inwardly-proj ecting semiglobular protuberance or enlargement f on its end and inner face, adapted to engage and iit in the twist of the casting, the twists being concaved in cross -section, as Shown.

When the churn-body is in place, the dasher is placed therein and the twist portion of casting D is slipped between bifurcations of the lever F by pressing the castingD toward the lever and slightly turning the casting. Then thumb-bolt c is screwed down into socket d, holding the dasher firmly in a vertical position. Then by vibrating lever F the protuberances f on its bifurcations rising and falling in engagement with the inclined twists of the casting rotate the latter, as is evident.

The device is Very simple and eliicient in operation.

I am aware that it is old to convert reciprocating motion into rotary motion by means of a twist-stock and nut and lever; but I believe my device is wholly novel and more simple and as eflicient as any prior devices of this character for the purpose described.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

l. In a churn, the combination of the churnbody, dasher, and twist portion on the upper end of dasher; with the vibrating lever having a bifurcated end embracing and directly engaging the twist portion of the dasher, for the purpose and substantially as described.

2. In a churn the combination of the churnbody, the dasher, having a twist portion on the outer end of its shaft; and means for securing said dasher in position While allowing it to be rotated; with the oscillating lever having a bifuroated end embracing and directly engaging the twist portion of the dasher, the bifurcations having inwardly-projecting protuberances on their ends for the purpose land substantially as described.

3. The combination in a churn, of the stand, the casting C mounted thereon having a thumb-bolt in its upper end, the churnbody,.its dasher, and the twist-casting D on the dasher-shaft; with the vibrating lever F my own I affix my signature in presene of pivoted to said casting C, and having a. bitwo Witnesses.

furcated end provided with enlarfrements f n n adapted' to directly engage the twists of the PE l ER CAHNNA 5 casting, al1 substantially as and foi-'the pur- Titnessesz J. F. L. COCHRAN,

pose described.

In testimony that I claim the foregoing as W. B. GREENLOW.
